How small are we in the scale of the universe?

« In 1995, scientists pointed the Hubble Telescope at an area of the sky near the Big Dipper. The location was apparently empty, and the whole endeavor was risky – what, if anything, was going to show up? But what came back was nothing short of spectacular: an image of over 1,500 galaxies glimmering in a tiny sliver of the universe. » Alex Hofeldt helps us understand the scale of this image.

A two-minute version of a 4-minute animated lesson for TED-Ed about Hubble Deep Field Images.
